A bedrock heat pump harnesses stored solar energy from the bedrock via a ground collector installed in one or more vertical boreholes, which can be up to 200 meters deep, the energy can then be used to provide space heating and hot water. This method of energy collection is ideal if the plot size is limited or if minimal impact on the plot is required, for larger installations where high levels of heat extraction are required multiple boreholes can be installed. It is always advisable to consult a specialist company regarding the design and installation of a vertical collector system.
